C＃でJSONを解析する
Google AJAX Search APIからのJSONデータを解析しようとしています。 このURL があり、結果が表示されるように分解したいと思います。私は現在このコードを書いていますが、単純化されたJSON文字列を使用した例は数多くありますが、次に何をすべきかについてかなり迷っています。
一般にC＃と.NETを初めて使用するため、ASP.NETページの正規のテキスト出力を取得するのに苦労したため、JSON.NETを試してみることをお勧めします。 Google AJAX Search APIからJSONを取り込んで画面に出力するコードを単に書くだけで、正しい方向に向けられる人はいますか？
編集：すべて修正済み！すべての結果は正常に機能しています。 Dreas Grech、ありがとうございました！

現在、コードは完全にコンパイルおよび実行されていますが、結果が返されていません。誰かが私が必要なものを返すのを手伝ってくれるでしょうか、結果を画面に印刷する準備ができていますか？

Json.NETは、上記の例と同じJSONとクラスを使用して動作します。

結果が返されなかった理由に気付きました... Deserializeメソッドに行がありません。結果をobjに割り当てるのを忘れていました：
public static T Deserialize<T>(string json)
{
using (MemoryStream ms = new MemoryStream(Encoding.Unicode.GetBytes(json)))
{
DataContractJsonSerializer serializer = new DataContractJsonSerializer(typeof(T));
return (T)serializer.ReadObject(ms);
}
}
また、参考のために、以下にSerializeメソッドを示します。
public static string Serialize<T>(T obj)
{
DataContractJsonSerializer serializer = new DataContractJsonSerializer(obj.GetType());
using (MemoryStream ms = new MemoryStream())
{
serializer.WriteObject(ms, obj);
return Encoding.Default.GetString(ms.ToArray());
}
}
編集
Json.NETを使用する場合、上記のコードと同等のSerialize/Deserializeメソッドがあります。
逆シリアル化：
JsonConvert.DeserializeObject<T>(string json);
シリアライズ：
JsonConvert.SerializeObject(object o);
これはすでにJson.NETの一部であるため、JsonConvertクラスで呼び出すことができます。

今、StackOverflowを取得する理由は、Propertiesが原因です。
これを例にとってみましょう：
[DataMember]
public string unescapedUrl
{
get { return unescapedUrl; } // <= this line is causing a Stack Overflow
set { this.unescapedUrl = value; }
}
getterでは、実際のプロパティを返していることに注意してください（つまり、プロパティのgetterが何度も何度も自分自身を呼び出している）。したがって、無限再帰を作成しています。
プロパティ（2.0）は次のように定義する必要があります。
string _unescapedUrl; // <= private field
[DataMember]
public string unescapedUrl
{
get { return _unescapedUrl; }
set { _unescapedUrl = value; }
}
プライベートフィールドがあり、ゲッターでそのフィールドの値を返し、セッターでそのフィールドの値を設定します。
ところで、3.5フレームワークを使用している場合は、これを実行してバッキングフィールドを回避し、コンパイラに処理させることができます。
public string unescapedUrl { get; set;}
JSONを動的オブジェクトに解析する で、DynamicObjectとJavascriptConverterを拡張して文字列をオブジェクトに変換するこのアプローチを見つけました。
DynamicJsonObject
public class DynamicJsonObject : DynamicObject
{
private IDictionary<string, object> Dictionary { get; set; }
public DynamicJsonObject(IDictionary<string, object> dictionary)
{
this.Dictionary = dictionary;
}
public override bool TryGetMember(GetMemberBinder binder, out object result)
{
result = this.Dictionary[binder.Name];
if (result is IDictionary<string, object>)
{
result = new DynamicJsonObject(result as IDictionary<string, object>);
}
else if (result is ArrayList && (result as ArrayList) is IDictionary<string, object>)
{
result = new List<DynamicJsonObject>((result as ArrayList).ToArray().Select(x => new DynamicJsonObject(x as IDictionary<string, object>)));
}
else if (result is ArrayList)
{
result = new List<object>((result as ArrayList).ToArray());
}
return this.Dictionary.ContainsKey(binder.Name);
}
}
コンバータ
public class DynamicJsonConverter : JavaScriptConverter
{
public override object Deserialize(IDictionary<string, object> dictionary, Type type, JavaScriptSerializer serializer)
{
if (dictionary == null)
throw new ArgumentNullException("dictionary");
if (type == typeof(object))
{
return new DynamicJsonObject(dictionary);
}
return null;
}
public override IDictionary<string, object> Serialize(object obj, JavaScriptSerializer serializer)
{
throw new NotImplementedException();
}
public override IEnumerable<Type> SupportedTypes
{
get { return new ReadOnlyCollection<Type>(new List<Type>(new Type[] { typeof(object) })); }
}
}
使用法（ サンプルjson ）：
JavaScriptSerializer jss = new JavaScriptSerializer();
jss.RegisterConverters(new JavaScriptConverter[] { new DynamicJsonConverter() });
dynamic glossaryEntry = jss.Deserialize(json, typeof(object)) as dynamic;
Console.WriteLine("glossaryEntry.glossary.title: " + glossaryEntry.glossary.title);
Console.WriteLine("glossaryEntry.glossary.GlossDiv.title: " + glossaryEntry.glossary.GlossDiv.title);
Console.WriteLine("glossaryEntry.glossary.GlossDiv.GlossList.GlossEntry.ID: " + glossaryEntry.glossary.GlossDiv.GlossList.GlossEntry.ID);
Console.WriteLine("glossaryEntry.glossary.GlossDiv.GlossList.GlossEntry.GlossDef.para: " + glossaryEntry.glossary.GlossDiv.GlossList.GlossEntry.GlossDef.para);
foreach (var also in glossaryEntry.glossary.GlossDiv.GlossList.GlossEntry.GlossDef.GlossSeeAlso)
{
Console.WriteLine("glossaryEntry.glossary.GlossDiv.GlossList.GlossEntry.GlossDef.GlossSeeAlso: " + also);
}
このメソッドはtrueを返す必要があります。そうでない場合、エラーがスローされます。例えば。キーが存在しない場合はエラーをスローできます。
trueを返し、resultを空にすると、エラーがスローされるのではなく、空の値が返されます。
public override bool TryGetMember(GetMemberBinder binder, out object result)
{
if (!this.Dictionary.ContainsKey(binder.Name))
{
result = "";
}
else
{
result = this.Dictionary[binder.Name];
}
if (result is IDictionary<string, object>)
{
result = new DynamicJsonObject(result as IDictionary<string, object>);
}
else if (result is ArrayList && (result as ArrayList) is IDictionary<string, object>)
{
result = new List<DynamicJsonObject>((result as ArrayList).ToArray().Select(x => new DynamicJsonObject(x as IDictionary<string, object>)));
}
else if (result is ArrayList)
{
result = new List<object>((result as ArrayList).ToArray());
}
return true; // this.Dictionary.ContainsKey(binder.Name);
}
データクラスがJSONオブジェクトと一致しません。代わりにこれを使用してください：
[DataContract]
public class GoogleSearchResults
{
[DataMember]
public ResponseData responseData { get; set; }
}
[DataContract]
public class ResponseData
{
[DataMember]
public IEnumerable<Results> results { get; set; }
}
[DataContract]
public class Results
{
[DataMember]
public string unescapedUrl { get; set; }
[DataMember]
public string url { get; set; }
[DataMember]
public string visibleUrl { get; set; }
[DataMember]
public string cacheUrl { get; set; }
[DataMember]
public string title { get; set; }
[DataMember]
public string titleNoFormatting { get; set; }
[DataMember]
public string content { get; set; }
}
また、逆シリアル化のために型を取得するためにクラスをインスタンス化する必要はありません。
public static T Deserialise<T>(string json)
{
using (var ms = new MemoryStream(Encoding.Unicode.GetBytes(json)))
{
var serialiser = new DataContractJsonSerializer(typeof(T));
return (T)serialiser.ReadObject(ms);
}
}
例全体が役立つと思います。これはこの問題の例です。
